Darwin Harbour Habitat Mapping Program: Probability of occurrence of seagrass habitat

This resource contains a probability of occurrence grid of seagrass for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The probability of occurrence grid of seagrass was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from a previous survey GA0333 collected by GA, AIMS and NTG-DENR.

本资源为达尔文港（Darwin Harbour）与拜诺港（Bynoe Harbour）海底基线测绘项目的组成部分，涵盖大达尔文港区域的海草出现概率栅格数据集。本项目资金由INPEX牵头的伊契斯液化天然气（Ichthys LNG）项目通过抵偿资金拨付至北领地政府环境与自然资源部（NTG-DENR），并由澳大利亚地球科学局（Geoscience Australia, GA）与澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）共同出资参与。本项目旨在通过整理与采集基线数据，深化对达尔文港及拜诺港海域海洋环境的认知，所获数据可用于生成专题生境地图与相关信息，为海洋资源管理决策提供支撑。本海草出现概率栅格数据集整合了GA、AIMS与NTG-DENR在2011至2017年间开展的多项调查数据，包括GA0333（Siwabessy等，2015）、GA0341（Siwabessy等，2015）、GA0351/SOL6187（Siwabessy等，2016）、GA4452/SOL6432（Siwabessy等，2017）、GA0356（Radke等，2017）以及GA0358与GA0359（Radke等，2018），并补充了此前由GA、AIMS与NTG-DENR开展的GA0333调查数据。
